The Brooklyn, NY bred rapper, who turns 44 today, has given himself a 22-day-vegan challenge after garnering some inspiration from a close friend.

Jay will be joined by his wife Beyonce in his goal to give up meat and dairy, and he will include fans in his process. Check out Jay's note via his Life+Times website.

Psychologists have said it takes 21 days to make or break a habit. On the 22nd day, you’ve found the way.

On December 3rd, one day before my 44th birthday I will embark on a 22 Days challenge to go completely vegan, or as I prefer to call it, plant-based!! This all began a few months back when a good friend and vegan challenged me to embrace a “plant-based breakfast” everyday. It was surprisingly easier on me than I thought…

Why now? There’s something spiritual to me about it being my 44th birthday and the serendipity behind the number of days in this challenge; 22 (2+2=4) coupled with the fact that the challenge ends on Christmas day…It just feels right!

So you can call it a spiritual and physical cleanse. I will post my progress… Any professional vegans out there that have any great food spots please help out! Please ha. I don’t know what happens after Christmas. A semi-vegan, a full plant-based diet? Or just a spiritual and physical challenge? We’ll see…
